小编Gau*_*dia的帖子

我使用链接https://firebase.google.com/docs/dynamic-links/ios对firebase集成进行了更改,以下是处理URL并将用户导航到相应屏幕的处理.对于低于9.0的iOS版本,调用appdelegate的openURL方法,我可以获取URL.但是对于iOS版本9.0及更高版本,我在app delegate的ContinueUserActivity方法中调用,并且我获得了dynamicLink.url的nil值.

我无法理解为什么我无法获取Url的原因.

- (BOOL)application:(UIApplication *)application continueUserActivity:(nonnull NSUserActivity *)userActivity restorationHandler:(nonnull void (^)(NSArray * _Nullable))restorationHandler {
       NSLog(@"Short URl : %@",userActivity.webpageURL);
       __weak AppDelegate *weakSelf = self;
       BOOL handled = [[FIRDynamicLinks dynamicLinks]
                 handleUniversalLink:userActivity.webpageURL
                    completion:^(FIRDynamicLink * _Nullable dynamicLink,
                                 NSError * _Nullable error) {
                         AppDelegate *strongSelf = weakSelf;
                         [strongSelf handleReceivedLink:dynamicLink];
                    }];
return handled;
}
-(void)handleReceivedLink:(FIRDynamicLink*)dynamicLink{
    NSString* urlString = [NSString stringWithFormat:@"%@",dynamicLink.url];
    NSLog(@"Extended URL : %@",urlString);
}
